Solved with your help, today I did the function I needed! Thanks!
I write a piece, maybe someone can help.
The function takes the title of a post-type related to products (woocommerce) and inserts this title as a woocommerce attribute when save_post action !

add_action('acf/save_post', 'update_post_meta', 20); 
	
function update_post_meta( $post_id ) { 
		
$post_type = get_post_type($post_id);
		
global $product; 
if ( 'product' == $post_type ) {
					
//TAKE RELATED INFO IN POST TYPE 
$posts = get_field('serie_di_appartenenza');
if( $posts ): 
foreach( $posts as $p ):
$scrittore=get_field("scrittore_appartenenza", $p->ID); 
if( $posts ): 
foreach( $scrittore as $s ): 
$scrittore_ereditato= get_the_title( $s->ID );
	
//ADD INFO IN GLOBAL ATTRIBUTE WOOCOMMERCE				
$term_taxonomy_ids = wp_set_object_terms( $post_id, $scrittore_ereditato, 'pa_scrittore-woo', true );
					
endforeach;
endif; 
endforeach;
endif; 

//ADD INFO IN CURRENT POST

$data = Array(

'pa_scrittore-woo'=>Array( 
'name'=>'pa_scrittore-woo', 
'value'=>$scrittore_ereditato,
'is_visible' => '1',
'is_variation' => '1',
'is_taxonomy' => '1'
),
);

//UPDATE META					
update_post_meta( $post_id, '_product_attributes',$data);
					
}
}
